I also do my reloading in batches. When I accumulate 300-500 spent dirty casings I deprime and clean on one occassion, then at another time I size and trim for lenght, then at another time I prime. By the time it comes to the actual weighing out powder and seating bullets I always have the 300-500 cleaned, sized and primed cases ready to go. I do this for both pistol and rifle rounds and always have 2000-3000 clean cases sized and primed in marked boxes ready to go. Trying to deprime, clean, size,trim, prime, measure powder and seat bullets all at the same time is just too much for my set up. I use a plain single stage Lee and it works quite well for me.
